To check for a putative effect of the 11 LDHH on embryonic, fetal and/or perinatal lethality in the dairy Lacaune population, two fertility-associated traits that could reflect the consequences of these mutations were analyzed: AI success (AIS: 1,155,835 matings) and stillbirth rate (SBR: 804,577 matings) (Fig. 1). This evidence concerns the gene LDHB and Stillbirth.
